I've got new world cichlids and had been feeding flakes, shrimp pellets, tetra color granules, and frozen shrimp and blood worms. They devour all those foods quickly. I bought Hikari staple because I heard how good they're supposed to be. The fish seem really uninterested in it. The oscars slowly grab them and eat a little and have a lot come out of their gills. Then while the food is sinking after it comes out of their gills the other fish will eat it. I tried presoaking the food in aquarium water before putting it in and only feeding a small amount of staple with no other food for a few days and still didn't seem to make a difference. It takes 15 to 20 minutes for them to eat less of the Hikari food than they would eat of the other in a few minutes. I even took out the Hikari food and put in other food to make sure they were hungry one day and of course it disappeared quickly. Any suggestions on how to get them to eat it or of another good food they might enjoy? Thanks.
